The single-page agreement, dated 12 November 1893, contains seven short articles, including a commitment not to exercise interference beyond the Durand Line.[1] A joint British-Afghan demarcation survey took place starting from 1894, covering some 800 miles of the border.[2][3] Established towards the close of the "Great Game", the resulting line established Afghanistan as a buffer zone between British and Russian interests in the region.[4] The line, as slightly modified by the Anglo-Afghan Treaty of 1919, was inherited by Pakistan.

The initial and primary demarcation, a joint Afghan-British survey and mapping effort, covered 800 miles and took place from 1894 to 1896. "The total length of the boundary which had been delimitated and demarcated between March 1894 and May 1896, amounted to 800 miles." Detailed topographic maps locating hundreds of boundary demarcation pillars were soon published and are available in the Survey of India collection at the British Library.[20] The complete 20-page text of these detailed joint Afghan-British demarcation surveys is available in several sources, which point out that "J. Donald and Sardar Shireendil Khan settled the boundary from Sikaram Peak (34-03 north, 69-57 east) to Laram Peak (33-13 north, 70-05 east) in a document dated 21 November 1894. This section was marked by 76 pillars. The boundary from Laram Peak to ... Khwaja Khidr (32–34 north) ... was surveyed and marked by H. A. Anderson in concert with various Afghan chiefs ... marked by (39) pillars which are described in a report dated 15 April 1895. L. W. King (issued a report dated) 8 March 1895 (on) the demarcation of the section from Khwaja Khidr to Domandi (31–55 north) by 31 pillars. The line from Domandi to New Chaman (30–55 north, 66-22 east) was marked by 92 pillars by a joint demarcation commission led by Captain (later Lt. ColonelSir) Henry McMahon and Sardar Gul Muhammad Khan (who issued a) report dated 26 February 1895. McMahon also led the demarcation commission with Muhammad Umar Khan which marked the boundary from new Chaman to ... the tri-junction with Iran ... by 94 pillars which are described in a report dated 13 May 1896."[21][22] In 1896, the long stretch from the Kabul River to China, including the Wakhan Corridor, was declared demarcated by virtue of its continuous, distinct watershed ridgeline, leaving only the section near the Khyber Pass, which was finally demarcated in the treaty of 22 November 1921 signed by Mahmud Tarzi, "Chief of the Afghan Government for the conclusion of the treaty" and "Henry R. C. Dobbs, Envoy Extraordinary and Chief of the British Mission to Kabul."[21] A very short adjustment to the demarcation was made at Arundu (Arnawai) in 1933–34.[3][21]

Shortly after demarcation of the Durand Line, the British began connecting the region on its side of the Durand Line to the vast and expansive Indian railway network. Meanwhile, Abdur Rahman Khan conquered the Nuristanis and made them Muslims. Concurrently, Afridi tribesmen began rising up in arms against the British, creating a zone of instability between Peshawar and the Durand Line. Further, frequent skirmishes and wars between the Afghan state and the British Raj starting in the 1870s made travel between Peshawar and Jalalabad almost impossible. As a result, travel across the boundary was almost entirely halted. Further, the British recruited tens of thousands of local Pashtuns into the British Indian Army and stationed them throughout British India and southeast Asia. Exposure to India, combined with the ease of travel eastwards into Punjab and the difficulty of travel towards Afghanistan, led most Pashtuns to orient themselves towards the heartlands of British India and away from Kabul. By the time of Indian independence, political opinion was divided into those who supported a homeland for Muslim Indians in the shape of Pakistan, and those who believed that a united India would be a better option. Having been cut off from Afghan life for approximately 70 years, no prominent political or religious figures voiced any support for reunification with Afghanistan.

Pakistan inherited the 1893 agreement and the subsequent 1919 Treaty of Rawalpindi after the partition from the British India in 1947. There has never been a formal agreement or ratification between Islamabad and Kabul.[26] Pakistan believes and international convention under uti possidetis juris supports the position that it should not require one;[11] courts in several countries around the world and the Vienna Convention have universally upheld via uti possidetis juris that binding bilateral agreements are "passed down" to successor states[27] Thus, a unilateral declaration by one party has no effect; boundary changes must be made bilaterally.[28]

At the time of independence, the indigenous Pashtun people[14] living on the border with Afghanistan were given only the choice of becoming a part either of India or Pakistan.[5] Further, by the time of the Indian independence movement, prominent Pashtun nationalists such as Abdul Ghaffar Khan and his Khudai Khidmatgar movement advocated a united India, and not a united Afghanistan – highlighting the extent to which infrastructure and instability together began to erode Pashtun self-identification with Afghanistan. By the time of independence, popular opinion amongst Pashtuns was split amongst the majority who wished to join the newly formed state of Pakistan, and the minority who wished to become a part of the Dominion of India.

Some scholars have suggested that memoranda from British officials in the 1890s suggest that the Durand Line was never intended to be a boundary demarcating sovereignty, but rather a line of control beyond which either side agreed not to interfere unless there were an expedient need to do so.[who?] These same scholars[who?] suggest that the frontier agreement was not of the form of an "executed clause", which usually caters for sovereign boundary demarcation and which cannot be unilaterally repudiated.[citation needed] And yet, within four years, joint Afghan-British demarcation teams had completed detailed demarcation surveys and demarcation text for most of the Durand Line (see above), contrary to the conjecture that the 1893 agreement was of the form of an "executory clause", similar to those pertaining to trade agreements, which are ongoing and can be repudiated by either party at any time. Other legal questions currently being considered are those of state practice, i.e. whether the relevant states de facto treat the frontier as an international boundary, and whether the de jure independence of the Tribal Territories at the moment of Indian Independence undermine the validity of Durand Agreement and subsequent treaties.[29][30]

His Majesty's Government in the United Kingdom has seen with regret the disagreements between the Governments of Pakistan and Afghanistan about the status of the territories on the North West Frontier. It is His Majesty's Government's view that Pakistan is in international law the inheritor of the rights and duties of the old Government of India and of his Majesty's Government in the United Kingdom in these territories and that the Durand Line is the international frontier.[32]

The members of the Council declared that their governments recognised that the sovereignty of Pakistan extends up to the Durand Line, the international boundary between Pakistan and Afghanistan, and it was consequently affirmed that the Treaty area referred to in Articles IV and VIII of the Treaty includes the area up to that Line.[33]

After the collapse of the pro-Soviet Afghan government in 1992, Pakistan obviously being aware of article 2 of the Durand Line Agreement, where it mentions "The Government of India (Pakistan) will at no time exercise interference in the territories lying beyond this line on the side of Afghanistan", created a puppet state in Afghanistan run by the Taliban.[38] According to a summer 2001 report in The Friday Times, even the Taliban leaders challenged the very existence of the Durand Line when former Afghan Interior MinisterAbdur Razzaq and a delegation of about 95 Taliban visited Pakistan.[39] The Taliban refused to endorse the Durand Line despite pressure from Islamabad, arguing that there shall be no borders among Muslims. When the Taliban government was removed in late 2001, the Afghan PresidentHamid Karzai also began resisting the Durand Line,[40] and today the present Government of Afghanistan does not recognize Durand Line as its international border. No Afghan government has recognized the Durand Line as its border since 1947.[41][42]

The Afghan Geodesy and Cartography Head Office (AGCHO) depicts the line on their maps as a de facto border, including naming the "Durand Line 2310 km (1893)" as an "International Boundary Line" on their home page.[43] However, a map in an article from the "General Secretary of The Government of Balochistan in Exile" extends the border of Afghanistan to the Indus River.[11] The Pashtun dominated Government of Afghanistan not only refuses to recognise the Durand Line as the international border between the two countries, it claims that the Pashtun territories of Pakistan rightly belong to Afghanistan.[10] Many in Afghanistan as well as some Pakistani politicians find the existence of the international boundary splitting ethnic Pashtun areas to be at least objectionable if not abhorrent.[44] Some argue that the 1893 treaty expired in 1993, after 100 years elapsed, and should be treated similarly to the Convention for the Extension of Hong Kong Territory.[11][12][13][39][45] However, neither the relatively short Durand Line Agreement itself nor the much longer joint boundary demarcation documents that followed in 1894-6 make any mention of a time limit suggesting the treaty should be treated similar to the Curzon Line and Mexican Cession or any other international boundary agreement (none of which have time limits.) In 2004, spokespersons of U.S. State Department's Office of the Geographer and Global Issues and British Foreign and Commonwealth Office also pointed out that the Durand Line Agreement has no mention of an expiration date.

Recurrent claims that (the) Durand Treaty expired in 1993 are unfounded. Cartographic depictions of boundary conflict with each other, but Treaty depictions are clear.[26]

Because the Durand Line divides the Pashtun and Baloch people, it continues to be a source of tension between the governments of Pakistan and Afghanistan.[46] In August 2007, Pakistani politician and the leader of Jamiat Ulema-e-Islam, Fazal-ur-Rehman, urged Afghanistan to recognise the Durand Line.[47] Press statements from 2005 to 2007 by former Pakistani PresidentMusharraf calling for the building of a fence on the Durand Line have been met with resistance from numerous Pashtun political parties within Afghanistan.[48][49][50][51][52][53][54][55] Pashtun politicians in Afghanistan strenuously object to even the existence of the Durand Line border.[44]

Aimal Faizi, spokesman for the Afghan President, stated in October 2012 that the Durand Line is "an issue of historical importance for Afghanistan. The Afghan people, not the government, can take a final decision on it."[9]

In July 2003, Pakistani and Afghan forces clashed over border posts. The Afghan government claimed that Pakistani military established bases up to 600 meters inside Afghanistan in the Yaqubi area near bordering Mohmand Agency.[56] The Yaqubi and Yaqubi Kandao (Pass) area were later found to fall within Afghanistan.[57] In 2007, Pakistan erected fences and posts a few hundred meters inside Afghanistan, near the border-straddling bazaar of Angoor Ada in South Waziristan, but the Afghan National Army quickly removed them and began shelling Pakistani positions.[56] Leaders in Pakistan said the fencing was a way to prevent Taliban militants from crossing over between the two nations but Afghan President Hamid Karzai believed that it is Islamabad plan to permanently separate the Pashtun tribes.[58]Special Forces from the United States Army have been based at Shkin, Afghanistan, seven kilometers west of Angoor Ada, since 2002.[59] In 2009, the International Security Assistance Force (ISAF) and American CIA have begun using unmanned aerial vehicles from the Afghan side to hit terrorist targets on the Pakistani side of the Durand Line.[60]

The border area between Afghanistan and Pakistan has long been one of the most dangerous places in the world, due largely to very little government control. It is legal and common in the region to carry guns, and assault rifles and explosives are common.[61] Many forms of illegal activities take place, such as smuggling of weapons, narcotics, lumber, copper, gemstones, marble, vehicles, and electronic products, as well as ordinary consumer goods.[46][62][63][64][65] Kidnappings and murders are frequent.[7] Numerous outsiders with extremist views came from around the Muslim world to settle in the Durand Line region over the past 30 years. While most of the time the Taliban cross the Durand Line from Afghanistan into Pakistan and carry out attacks inside Pakistani cities, sometimes they cross from the Pakistani side of the border and attack Afghan security forces. Recently, 300 Taliban militants from Afghanistan's territory launched attacks on Pakistani border posts in which 34 Pakistani security forces were believed to be killed. It is also believed Swat District Taliban leader Maulana Fazlullah is hiding somewhere inside Afghanistan.[66] In June 2011 more than 500 Taliban militants entered Upper Dir area from Afghanistan and killed more than 30 Pakistani security forces. Police said the attackers targeted a checkpost, destroyed two schools and several houses, while killing a number of civilians.[67]

The governments of Pakistan and Afghanistan are both trying to extend the rule of law into the border areas. At the same time, the United States is reviewing the Reconstruction Opportunity Zones (ROZ) Act in Washington, D.C., which is supposed to help the economic status of the Pashtun and Baloch tribes by providing jobs to a large number of the population on both sides of the Durand Line border.[68]

Much of the northern and central Durand line is quite mountainous, where crossing the border is often only practical in the numerous passes through the mountains. Border crossings are very common, especially among Pashtuns who cross the border to meet relatives or to work. The movement of people crossing the border has largely been unchecked or uncontrolled,[46] although passports and visas are at times checked at official crossings. In June 2011 the United States installed a biometric system at the border crossing near Spin Boldak aimed at improving the security situation and blocking the infiltration of insurgents into southern Afghanistan.[69]

Between June and July 2011, Pakistan Chitral Scouts and local defence militias suffered deadly cross border raids. In response the Pakistani military reportedly shelled some Afghan villages in Afghanistan's Nuristan, Kunar, Nangarhar, and Khost provinces resulting in a number of Afghan civilians being killed.[70] Afghan sources claimed that nearly 800 rounds of missiles were fired from Pakistan, hitting civilian targets inside Afghanistan.[71] The reports claimed that attacks by Pakistan resulted in the deaths of 42 Afghan civilians, including children, wounded many others and destroyed 120 homes. Although Pakistan claims it was an accident and just routine anti Taliban operations, some analysts believe that it could have been a show of strength by Islamabad. For example, a senior official at the Council on Foreign Relations explained that because the shelling was of large scale it is more likely to be a warning from Pakistan than an accident.[72]

I'm speculating, but natural possibilities include a signal to Karzai and to (the United States) that we can't push Pakistan too hard.[72]

The United States and other NATO states often ignore this sensitive issue, likely because of potential effects on their war strategy in Afghanistan. Their involvement could strain relations and jeopardise their own national interests in the area.[10]This came after the November 2011 NATO bombing in which 24 Pakistani soldiers were killed.[73] In response to that incident, Pakistan decided to cut off all NATO supply lines as well as boost border security by installing anti-aircraft guns and radars to monitor air activity.[74] Regarding the Durand Line, some rival maps are said to display discrepancies of as much as five kilometers.[75]

In June 2016, Pakistan announced that it had completed a 1,100 km trench along the Pakistan-Afghanistan border (Durand Line) in Balochistan to check movement of terrorists and smugglers across border into Pakistan from Afghanistan.[76]

In 1893, the British and the Afghan Amir (Abdur Rahman Khan) agreed to set up the Durand line (named after the foreign Secretary of the Indian government, Sir Mortimer Durand) to divide Afghanistan and what was then British India.
